I have a small inverter that runs off the 12 V in the car. I use it for charging while traveling sometimes. I plug the Nikon charger into it.But for the price of an inverter, you can almost buy another battery. I would budget the battery as part of my road trip expenses, or find some way to scrape up the price of the battery beforehand.You are right, the flash does consume a lot of battery. But you may not need it so much in the daytime & outdoors.
